15.4.3.2 Setting hardware write-protection
The flow meter is equipped with a write protection function. It can be set via DIP SW1-2
behind the display. Use a sharp-pointed object to set the switch.
The flow meter can be protected from unauthorized access. If the software write-
protection via WRITE LOCKING is not adequate, an additional hardware write-protection
can be set on the main board of the transmitter. With the write-protection active, the
transmitter display can still be operated, any changes to settings or parameters are not
saved and therefore not effective.
Write-protection can also be activated without removing the display. To do this, remove
the jumper from the write-protection terminal (see Inputs and Outputs in chapter Setting
methods).
It is not possible to release the hardware write-protection via PROFIBUS PA
communication software.
Factory setting
The factory setting of the Write protection mode is Low.
